Abstract: The fillable closure is used to trigger the emptying of a capsule that can be inserted in the closure and filled separately. The closure consists of a closing cap which can be attached to the neck of a container and in which a separately fillable capsule can be inserted in the closed state from beneath. The region above the inserted capsule on the closing cap forms a push button. A downwardly projecting protuberance is molded on the lower face. The protuberance abuts against the inserted capsule. Using pressure from above, the push button can be pressed to deform an initially convex shape as seen from above into a concave shape, the protuberance pushing the upper face of the capsule and the content thereof downward. A film, which forms the lower face of the capsule, is thus placed under tensile stress such that it breaks or bursts along weakened lines.

Abstract: The fillable closure with a triggering pushbutton comprises a filler neck (3) that is to be screwed onto or joined to a container neck (4) as well as a closure cap (1) which is associated to the filler neck (3) and can be joined, pivoted and snapped-on the filler neck (3) by means of a hinge connection. A separately fillable container (2) can be inserted into the filler neck (3), the container being closed at the bottom with a sealing foil (19) that can be pierced or cut open. The closure cap (1) comprises a cap cover as a pusher disc (7), which can be pressed downward in the axial direction while deforming. By pressing the cap cover downward on the container (2) inserted in the filler neck or on a rigid opening element accommodated therein, the opening element can be pressed downward so that the sealing foil (19) of the container (2) can be pierced and cut open.
